Answer:
total drop per minute is 56
Step-by-step explanation:
Give data:
total capacity of bag 1 L = 1000 ml
Duration of infuse 6 hr
quantity at the time delivered is 20 gtts/ml
Drop per minute can be determined by using following relation
Drop per minute 
therefore total drop per minute is
The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.
<h3>
Inequality</h3>
Inequality is the non equal comparison of two or more numbers and variables.
Let x represent the number of wallpapers and y represent the number of cans.
He needs at least 30 rolls of wallpaper and at least 20 cans of paint. Hence:
x ≥ 30 (1);
y ≥ 20 (2)
Also:
32x + 28y ≤ 2240 (3)
Plotting the 3 equations using geogebra online graphing tool, the possible solution is:
(30, 20), (30, 46)
The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.

Find the slope: m=(6-8)/[5-(-1)]=-1/3
y=-1/3 x+b
find b: 8=-1/3 *(-1)+b =>b=23/3
so the equation is f(x)= -1/3 x + 23/3
$42, you can do 60 x 0.3 which is equal to 18 and then do 60 - 18 and you get 42
